The jury in Kelli A. Jacobsen's manslaughter trial spent 6 1/2 hours deliberating Wednesday without reaching a verdict.
The 12-member panel will resume talks today in Benton County Superior Court.
Jacobsen, 28, is accused of causing the injuries that killed Ryder Morrison on June 22, 2011. She was the 1-year-old's live-in nanny.
Prosecutors allege Jacobsen was tired after staying up late the night before and either shook or hit the toddler.

On Wednesday morning, jurors asked to listen to Jacobsen's 911 call. It was played one time for them in the jury room.
Then later Wednesday, their request to get a transcript of Dr. Daniel Selove's testimony was denied. Jurors reportedly were given the standard response that they must rely on their memory of the forensic pathologist's testimony and their own notes.
